Drainage basin pollutant monitoring system and monitoring method thereof

Abstract

The invention belongs to the technical field of river environmental protection and discloses a drainage basin pollutant monitoring system and a monitoring method thereof. The drainage basin pollutantmonitoring system comprises a monitoring platform, a plurality of monitoring stations and a plurality of detection units. The method comprises the following steps of S1, establishing a river model ofa current drainage basin, and marking the positions of the monitoring stations, the positions of the detection units and altitude data; S2, collecting river water quality data and river surface garbage data; and S3, on the basis of a river model, transmitting the river water quality data and the river surface garbage data in the same flow direction to a monitoring station located at an upstream junction point of the flow direction for analysis and processing to obtain main pollutants, pollution levels and pollution source positions of the main flow and each branch flow, and sending the main pollutants, the pollution levels and the pollution source positions to a monitoring platform for display. The method is advantaged in that problems that in the prior art, the consumption of manpower andmaterial resources is large, real-time performance is poor, and a pollution source cannot be accurately positioned are solved.

Description

technical field [0001] The invention belongs to the technical field of river environmental protection, and in particular relates to a river basin pollutant monitoring system and a monitoring method thereof. Background technique [0002] At present, with the continuous improvement of my country's economic level, the water environment is facing various pressures such as water pollution, water resource shortage and flood disasters. Groundwater in sea areas and some areas has been polluted to varying degrees. Rivers are dominated by organic pollution, and the main pollutants are ammonia nitrogen, biochemical oxygen demand, permanganate index, and volatile phenol; lakes are characterized by eutrophication, and the main pollution indicators are total phosphorus, total nitrogen, and chemical oxygen demand. and permanganate index, etc.; the main pollution indicators in coastal waters are inorganic nitrogen, active phosphate and heavy metals. These factors constitute the characteris...
